Those in Melbourne will remember that some guy was attempting to ride the entire train network of Melbourne in one day. He did it successfully and made it on the news. http://melbourne.metblogs.com/2008/06/17/guy-tries-to-ride-o… (shameless self plug)
The story behind it is that he made a list of 183 things to do before he turned 30. One of them was the train one, another is to meet Richard Branson, etc.
Well he is giving 183 magnets out.
I hope he stopped for a schooner of beer at each stop, or it just doesn't count.
